Hi,
This is my first posting and I'm sorry if this question has been asked before.

I have a 2003 Sonoma and I would like to know if someone makes a conversion kit that will enable me to put lock-out hubs on my truck. I'm trying to get better gas mileage and I know that if I can do this it will help alot.

Thanks,
mingpau

no way to do it on chevy IFS. if you swap in a solid axle or toyota IFS(duno why anyone would do that, or if its even possible). Your IFS has a center axle disconnect so the halfshafts and spider gears turn in 2wd but not the ring & pinion or front driveshaft.
